At the Game Developers Conference (GDC) and other events like GDC Europe and Gamescom, game developers use Redis for various purposes including leaderboards, sessions, profiles, caching, and real-time data management. Online, social, and mobile games require strict latency and performance requirements, making Redis a suitable choice. Ad networks also heavily rely on Redis due to its speed and ability to handle high volumes of requests. The flexibility of Redis is appealing to developers, who often implement custom solutions using Lua scripts or modify the existing code. This versatility has led to creative uses in game development, such as implementing player matching mechanisms.
